Pretty awesome... I used to make all sorts of stuff from this clay, As far as i can remember, it doesnt give off any fumes, I used ot use our toaster oven and it was the one we made our food in too...lol I think youll be fine but, if you have an old toaster oven you can use, use it, its alot faster and less $$$ than heating up the big oven for a small item like this. You can also use the small oven to cure powder coated parts, as long as they are small enough to hang in it that is! lol But THAT WILL destroy your wife's new oven for sure!! lol

Polymer clay doesn't give off fumes, but it's always a good bet to use a dedicated toaster oven for polymer clay work. Wastes less energy. Doesn't make sense to heat up a whole oven just to bake a small piece of polymer sculpture.

I learned the hard way that baking in a toaster oven is a bad idea--the temperatures are just too inaccurate. Instead, make a baking vessel for your PC: buy two matching disposable aluminum pie plates. When you're ready to cure your clay, place it in one pie plate and turn the other over it upside-down, as a lid, then, take a long strip of heavy-duty aluminum foil and crimp it tightly all the way around the join of the two plates. Bake the clay, as directed. Any fumes will be contained in the vessel.

Polymer Clay DOES give off toxic fumes if it starts to burn so monitor it (you can see the smoke) because though your oven says a certain temperature, it can actually be running higher or lower. Cooked properly, it will not harm you :)

I don't think polymer clay is a great product for this project, it has little/no flexibility so is highly likely to crack, chip or break with regular use, or if the cord gets snagged. Sorry. I like the shape, and it is a good idea, but I think Sugru would be more likely to stand up to use.

Actually, different types of PC are more or less structurally strong, and Premo Sculpey is one of the stronger ones--the best is Donna Kato Polyclay, though it's not as easy to find (online being your best bet). Also, preconditioning the clay is important to ensure a strong final product--that is, you need to roll and stretch it repeatedly, until it softens and is flexible. Finally, if you're concerned about flexibility, there is a flexible clay, but I say, Premo or Kato will do very well.
